The Excellent Eco-Friendly Features of Carrozzeria

Pioneer is engaged in creating products that realize "Eco-Friendliness, Economy, and Enjoyment" in the car-driving experience. In car navigation systems, Pioneer's original Smart Loop function searches for an eco-friendly route that avoids traffic congestion to reduce fuel consumption and shorten the driving time to the destination. With car AV products, we have made each product small in size and lightweight, and reduced power consumption to lessen the load on the car in which the product is installed, contributing to fuel consumption improvement. Products of smaller size and lighter weight also contribute to the reduction of transport fuel for delivery of products to customers. Further, all Carrozzeria products are provided with substantial AV functions thoroughly focused on realizing high quality sound, high quality image, and advanced functions to make driving even more pleasant. Environment-friendliness, Economy, and Enjoyment" are continually pursued in Carrozzeria. Furthermore, by fully making good use of Green IT Technology as well, the consolidation of data centers for the management and operation of the car navigation data system was achieved, realizing significant reductions in electrical power consumption.

Have you ever had the experience of going roundabout because of making a wrong turn despite having a car navigation system? Pioneer considers that one of the important missions of car navigation systems to reliably give navigation instructions to the driver during driving to reduce waste of fuel and time. In addition to the Eco-route Search that reduces the fuel consumption by approximately 20% and the AR Scouter mode that helps alleviate traffic congestion, the Cyber Navi system (AVIC-VH99/ZH99 Series*1) realizes safe and comfortable eco-driving with the ultimate in intuitive guidance by the world's first*2 "AR HUD (Head-Up Display)" that projects carefully selected information in one's line of sight. This system is an ultimately eco-friendly car navigation system that provides reliable navigation along routes of minimum fuel consumption.

*1 Cruise Scouter unit (sold separately) is required, except for the AVIC-VH99 HUD and AVIC-ZH99 HUD. See the product pages for more details.*2 Among vehicle head-up displays using a laser (Pioneer survey, as of May 8, 2012)

We developed a navigation unit that will not mistake the direction in which one's car is proceeding and is also environment-friendly. This was realized with the cooperation of members of the HUD Development, Planning, Production, and Quality Assurance divisions. We shall continue to make environment-friendly products that are loved by everyone.

The "Carrozzeria" car navigation systems have been acknowledged for the original environmental technologies that reduce the fuel consumption in equipped cars and have been awarded with numerous environmental awards. The Cyber Navi model was awarded with the Eco-Products Award in 2008 for the Smart Loop function that avoids traffic congestion and reduces fuel consumption and was doubly awarded with the Green IT Award and the Green Purchasing Award in 2010 for the original fuel consumption estimation technology of the Eco-route Search function that informs of the fuel consumption before driving. Also, the Pioneer Demand Bus (shared taxi) system that secures a transportation means for residents of mountainous villages and contributes to reduction of use of personally-owned cars, etc., was awarded with the Green Purchasing Award (jointly awarded together with Iizuna Town of Nagano Prefecture).

The original fuel consumption estimation technology that we developed has made possible the Eco-route Search function, which informs of the fuel cost before driving, as well as the absolute fuel cost and eco status displays. In addition to taking the challenge to be the first in the industry and performing thoroughgoing verification of actual driving data and checking of usage feelings, etc., the teamwork of the staff lead to these achievements. We considered that eco-driving may be felt as being troublesome because sudden start and acceleration are prohibited, idling must be refrained from, etc. We thus equipped playful functions, such as checking of the degree of eco-friendliness by graphic displays and voice. With the advanced Cyber Navi technology, high quality is provided with gentleness and familiarity. These functions are inherited in subsequent models. Please experience the joy of eco-driving and its effects.

The Great East Japan Earthquake that occurred in March, 2011 severed numerous roads. With the wish for the earliest possible recovery of the disaster areas, Pioneer disclosed road information utilizing the Smart Loop information. The Carrozzeria car navigation system enabled checking of passable roads near the disaster areas. The passable roads contributed to the earliest possible recovery and also reduced wasteful driving caused by dead ends and thereby contributed to fuel reduction.


"Smart Loop" Contributed to Restoration of Disaster-Struck Areas

Not "Maybe Passable or Should-be Passable Roads," but "Passable Roads" are Displayed

Car navigation system screen images [differences between April 1 (left) and thereafter (right)]

The passable roads can be checked by display of VICS information ("passage prohibited (black solid lines)", "smooth traffic (blue solid lines)" along highways, etc.) and smart loop congestion information ("smooth traffic (blue dotted lines)," "congested (orange dotted lines)," etc.).

Certificate of Appreciation from the Minister of Land, Infrastructure, and Transportation

Further Support

A certificate of appreciation was conferred from the Minister of Land, Infrastructure, and Transportation to the incorporated NPO, ITS Japan, for integrating and consolidating probe information (passage record information) collected by Pioneer and automakers. As a car electronics maker, only Pioneer participated in the disclosure of passage record information.

As further support, 50 of Pioneer's AVIC-T05II car navigation systems, which enable checking of passable roads, were donated to the Property Administration Division of the Department of General Affairs of the Yamagata Prefectural Office on 12 April 2011.This was carried out from the wish for Pioneer's Smart Loop and the car navigation system to be utilized in route guidance for transport of personnel and materials for official duties, such as assistance to disaster areas, etc. from Yamagata Prefecture, which was comparatively low in damage, to provide as much aid as possible for the restoration of the disaster areas.

Pioneer is also engaged in reducing the electric power necessary for operation of car navigation data. The Smart Loop, which supports comfortable eco-driving by avoidance of congestion, is founded on a vast amount of information and much power is required for storage and management of the data. Pioneer thus took on the challenge of effectively using IT resources and by introduction of a cloud system making full use of virtualization technologies and by server/storage/network integration, replaced the 600 physical server units with 33 blade servers. As a result, the previously 6 data centers were consolidated into a single center and the power necessary for data management was reduced by 87.5%. The significant power reduction making full use of green IT technologies was appraised for the environmental contribution and was awarded the 2012 Kawasaki Environmental Show Window Award hosted by Kawasaki City, Kanagawa Prefecture.

With the advanced digital technology Class D amplifier adopted in our car power amplifiers, significant reductions in size and weight were achieved while realizing high power surpassing that of previous products. The reduced size enables installation in a small space as well as installation of multi-amplifier units to realize a substantial system upgrade. The light weight alleviates the load on the equipped car and reduces fuel consumption during driving. Further, the reductions in size and weight improve the transport efficiency for delivery to our customers and reduce the transport fuel and CO2 emitted during transport. Also, the class D amplifier is capable of high efficiency amplification and thus reduces power consumption. This reduces the load on the engine of the equipped car and leads to fuel consumption reduction.


High-Power Car Power Amplifiers are also Eco-Friendly
